PIN PAPEB-FASTENER.

' Application filed February 27, 1909. Serial No. 480,467.

To all whom it may concern:

Be it known that I, IRvrN RITTENHOUSE, a citizen of the United States, residing at Glen Echo Heights, in the State ofldaryland, have invented new and useful Improvements in Pin Paper-Fasteners, of which the following is a specification.

This invention relates to paper fasteners and more particularly to that type known as pin fasteners.

Theobject of this invention is to provide a fastening means by which a number of papers may be detachably secured together for the purpose of filing. To constitute a fastener of this description I provide a base portion havin struck up parallel extensions and a detachable pin fastener which may be removably secured thereto, and which will pass under the end portions and over the main portion of the base. The pin fastener is then bent up over the ends of the base to receive the papers to be secured.

The advantages of a device of this description are many, the most important being that as the pin fasteners are usually made from a strip of metal they do'not need to be bent in any particular form, as'they are most 1 readily attached to the base when perfectly :(lat, it only being necessary to insert a pin fastener through the apertures )rovided between the main portion of the ass and the struck up extensions, and when they are in position they are bent up over the ends of the extensions, which will always insure the same relation between those'portions of the pin fastener which are inserted through the papers to be held thereby. By this construction the outer side of the main portion of the base presents a flat surface to which a backin or index sheet may be secured by any well nown means, and the pin fastener may be removed and a new fastener supplied without interfering-with the backing or index sheet attached to the base portion.

The simplicity of construction and the adaptability of the base to the pin fasteners now in use are features of utmost advanta e.

The preferred form is illustrated int e accompanying drawings, yet it is to be understood that minor detail changes may be made without-departing from the scopeof the invention.

1 represents the pin fastener, which is prefera ly a long narrow strip of brass or other flexible metal.

2 indicates the base member preferably constructed of tin.

3 and 3 are the end ortions of the base struck up from the main ody and extending parallel therewith.

i and 4 are apertures in the angular portion between the main body of the base and the struck up end portions. These apertures are of sufficient size to receive the pin fastener 1.

5, 5 are outwardly extending prongs struck up from the face of themain body of the base opposite the struck up end portions, and 5*, 5 are projections extending from the edges of the main portion of the base.

The operation of my fastener is as'follows: The pin fastener and base are assembled by inserting the pin fastener through the apertures 4 and 4 and the ends of the pin are then bent up over the ends of the extensions 3 and. 3 in a position at right angles to the base. The fastener is then ready to receive the papers to be secured thereby. The papers may be previously (punched if desired,'

tearing of the outermost sheet a metallic washer 6 having apertures 6 adapted to receiv the ends of t then asten- The 5 and 5 on the back or edges of 10 pin fasteners ma be placed over the top sheet and the projections the .base member are arranged to secure a backing for the papers or an index sheet.

In forming the apertures 6 in the washers 6, the metal nearest the ends is struck up as at 7 to form a curved rest for a pin fastener asshown in Fig. 5. When-the washer is placed over the cm s of the pin fastener the projections 7 are on the underside, and also act as a guide for the pin fastener in finding the apertures 6.

fi ers struck up (prongs on the upper side of the washer 6, an

are'adapted to secure a label or facing sheet.

, and the nibs 9 may e struck up from the basal to engage the curved portion 8 of the Figs. 7 and 8. In this form the washer plate Wire to. secure in osition the fastener 1*.

A further mo ification is illustrated in 10- extends a considerable distance on each side of the pin openings 10 11 is a protectin plate corresppnding in'size and shape to was er 10'and centrally pivoted thereto at -12. Each end of washer 10 is provided with bent over portion 10 arranged to engage the ends of plate 11. -'The pin openings 10 are provided with downwardly projecting ortions 7 to assist the pin opemn sin locatmg the receiving openings 10 is swung to the position shown in Fig. 7, the pin fasteners passed through the openings provided therefor in the washer, bent out Wardly as shown, the late 11 moved to cover Washer 10 and then a the parts will be held secured by the bent over portions 10 engaging late 11.
